Don't let drivetrain drag steal those hard-earned watts and instead dial in your drivetrain speed with the smooth spinning UFO Chain KMC 11 Speed. This chain is crafted and optimized by hand in Denmark using race proven techniques and lubes designed to help you go faster with less effort. Two to five-watt savings are to be expected and this particular KMC 11-speed chain will work with SRAM, Campagnolo, and Shimano 11-speed road drivetrains.

We'd recommend using the chain just on race day as its efficiency begins to drop off after around 600 km or 370 miles of clean and dry riding. The UFO treatment is not optimized for wet and muddy conditions, sorry mountain bikers and 'cross racers, and might cause chain corrosion. The CeramicSpeed UFO Chains go through a multi-step process that involves polishing the link's sliding surfaces, cleaning off the inefficient factory lube, and the application of two layers of treatment to achieve the chain's best possible efficiency.

A wax base is utilized and applied at a specific temperature, as it was discovered through testing, to be the most efficient. Several recipes of different ratios of additives to the base were tested until the most efficient formula was achieved. Finally, Teflon powder is applied to the chain for maximum friction reduction. CeramicSpeed recommends the use of Squirt chain lube during maintenance intervals to keep the optimization going for as long as possible.
